cordova android app - webpage not available error ( quasar v15.10 )

Hi,
i have developed an application in Quasar14.9 which was good. now i converted the whole app in Version15.10 and build android apk using quasar dev -m cordova -T android but the new version is very slow. sometime i got the error Webpage not available

in route.js i tryied both lazy load / code split and load all layouts/pages/components into the initial bundle .

if i load all layouts/pages/components into the initial bundle the performance is better but not like version 14.9.
